1 Blood basophils from cystic fibrosis patients with allergic bronchopulmonary aspergillosis are primed and hyper-responsive to stimulation by aspergillus allergens  Yael Gernez, Colleen E. Dunn, Cassie Everson, Erin Mitsunaga, Lakshmi Gudiputi, Karolina Krasinska, Zoe A. Davies, Leonore A. Herzenberg, Rabindra Tirouvanziam, Richard B.

2 Fig. 1 Surface CD203c, CD63 and CD123 levels in blood basophils at baseline in CF-ABPA, CF-AC and CF patients. Shown are box plots (delimited by 25th and 75th percentiles, with median line and whiskers respresenting 10th and 90th percentiles) for CD203c, CD63 and CD123 levels in blood basophils from CF (N=12, light grey) patients, CF-AC (N=12, dark grey), CF-ABPA (N=11, black). Differences between groups were evaluated with the Wilcoxon rank-sum test. Non-significant differences are omitted.

3 Fig. 2 Surface CD203c levels in blood basophils upon ex vivo stimulation with Af (offending) or peanut (non-offending) allergen extracts. Shown are box plots for CD203c levels in blood basophils from CF (N=12, light grey), CF-AC (N=14, dark grey) and, CF-ABPA (N=11, black) patients upon 10-minute (top) and 30 minute (bottom) allergen stimulation. Differences between groups were evaluated with the Wilcoxon rank-sum test. Differences between Af and peanut stimulations within each group were evaluated with the Wilcoxon signed-rank test. Non-significant differences are omitted. Journal of Cystic Fibrosis  , DOI: ( /j.jcf ) Copyright © 2012 European Cystic Fibrosis Society. Terms and Conditions

4 Fig. 3 Plasma TARC (CCL17) and supernatant histamine measurements in samples from patients with CF, CF-AC and CF-ABPA. (A) Shown are box plots for baseline TARC levels in plasma from CF (N=11, light grey), CF-AC (N=13, dark grey), and CF-ABPA (N=11, black) patients. There were no significant differences in within- and between-group analyses. (B) Shown are mean and standard deviation for histamine levels in blood aliquots from CF (N=8, light grey), CF-AC (N=8, dark grey), and CF-ABPA (N=9, black) patients upon 10-minute (top panels) and 30 minute (bottom panels) allergen stimulation. There were no significant differences in within- and between-group analyses. Journal of Cystic Fibrosis  , DOI: ( /j.jcf ) Copyright © 2012 European Cystic Fibrosis Society. Terms and Conditions

5 Fig. 4 Activation of blood basophils from patients with CF-ABPA following ex vivo stimulation with rAsp f1. (A) Shown are box plots for surface CD203c levels in blood basophil following ex vivo stimulation for 30 minutes with rAsp f1 in CF (N=9, light grey), CF-AC (N=10, dark grey) and, CF-ABPA patients (N=8, black). (B) Titration of the antigen rAsp f1 at 10-minute (top panel) and 30-minute (bottom panel) of stimulation. Shown are histograms for CD203c surface expression in a representative subject with CF-ABPA.
